So yeah there is a person who never forgets my birthday. Never! We know us from school. More than 4 years now. The person studies in a town a couple of hours away. We see us rarely. No, my birthday is not on facebook (dont have fb) or another social media platform. I keep my birthday a "secret" without telling people that I keep it a secret. Just a few people know my birthday. The person always remembers my birthday! This is somehow scary and crazy. When I think back I can't remember any "signs". Just the fact that the person was acting shy when I was around. Never had deep smalltalk We also chat or see us rarely since school.

Does this mean something or is this person just nice?
